Patented May 23, 1922.

Application filed Novemberll, 1920. Serial No. 423,316.

Tofall whom it may concern Be'it known that'I, JAMES CLAYTON, af 'subject'of the Kin of Great Britain and Ireland, and a resi ent of Sebakwe, Babbacombe, county of Devon, England, and hav-'.

ing apost-ofiice address at Sebakwe, Babbacombe, county of Devon, England, have invented certain new and useful Improvements in Spinning Boxes for 'Artificial'Silk, of which-the following is a specification.

My I inventionrelates to apparatus for spinning artificial silk, and particularly to the spinning box. The object of the'present invention is to provide a rotary box support of improved construction, which mayv be used to advantage w th a box of the type shown in my application of even date hereor base and held thereto by centrifugally operated means, The present invention relates particularly to the rotary base or "sup-' 85 port on which the box proper is mounted,

-method of securing the face plate in the body of the support.

In my a spinning box which comprises a basket like body or cover fitting upon a rotary support and presents certain features of improve ment; I

The base 5 may be formed in'any suitable manner, preferably by casting',' and comprises a hub 6 provided with a cone bushmg7, into whichisdriv'en the taper end 8 of the rotary spinning spindle- 9. The co'ned peripheral flange 10 of the base is channeled at 11 to receive a ring 12' of soft rubber or the like. Below this channel is a shoulder- 1upon whichrests the lower edge of the spinning box proper: 1130f any suitable construction, the side wall of which sleeves upon the base and embraces the ring 12,

prior application Serial No. 227,348, filed April 8, 1918, I have described scribed.

When the apparatus in operation, the spindle 9is very rapidly rotated. Thisflcauses the elastic rubber ring 12- to expand under centrifugal force, and it engages and retains the'box 13 with a velvet grip. As soon as the spindle is halted, the ring'12 contracts by reason of its inherent elasticity and releases its grip on the box so that the latter may be freely lifted to remove the spun I fiber'cake. v I

To prevent discoloration ofthe cellulose fiber by contact with the metal body of the' base 5 in the presence of the'acids carried into the box by the. filaments, I provide a facing plate 15 which completelyoverlies the base. To secure this'in positlon the periphery of the plate is undercut at 16, while the base 5 is provided with a marginal flange 17 which, after the lining plateis placed in holds the tion;

.Various modifications will readily occur to those dealing with the problem,-. which do plate rigidly in assembledposinot depart from what I claim as my invention..'

In apparatus for spinning artificial silk, a' rotary base for a spinning box, said base having a peripheral'channel, and an- 'expansible' rubber ring lying in said channel Wall of a box' sleevin upon said base, subsilk, a rotary support, for a spinning box,

said support comprising a base having an lip-standing marg nal flange, and a facing plate overlying saidbase and flange and pe-g ripherally I undercut to receive and be grlpped by said flange, substantially as de I In testimony whereofl have signed my name to thisspecificatiom JA ES CLAYTON.
